Specification of Letters Patent.

Patented July 16, 1918.

Application filed June 29, 1917. Serial No. 177,748.

To all whom it may concern:

Be it known that I, ARNOLD STORUD, a citizen of the United States, and resident of Farm Park River, in the county of Walsh and State of North Dakota, have invented a certain new and useful Improvement in Bob-Sleds. of which the following is a specification.

The present invention relates to vehicles, and more particularly to the mounting and bracing of runners for bob sleds.

An object of the present invention is to provide an adjustable connection for runners to hold the same in various transversely spaced-apart positions for varying the tread of the vehicle and to accommodate it to widely and closely spaced-apart ruts in a roadway.

Another object of the present invention is to provide an improved mounting and connection for the body bolsters of the vehicle to retain the same on the runners at all adj ustments of the latter.

The above, and various other objects and advanta es of this invention will be in part described, and in part understood, from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings wherein Figure l is a side elevation of the running gear of a bob sled constructed according to the present invention.

Fig. 2' is a top plan view of the same, the body bolsters being removed.

Fig. 3 is a transverse section, enlarged, taken on a transverse plane indicated by the line 33 in Fig. 1.

Fig. 4 is a horizontal section taken in a plane indicated by the line 4-4 of Fig. 1.

Fig; 5 is a detail vertical section taken through one of the forward cross bars in a plane indicated by the line 5-5 of Fig. 1, the runners being omitted.

Fig. 6 is a similar View taken on a plane indicated by the line 6-6 in Fig. 1, the runners being omitted.

Fig. 7 is a detail perspective View of one of the supporting blocks and an adjacent sleeve or head adapted to seat upon the same, the block and the head being shown separated.

Referring to these drawings, 10 designates a pair of forward runners which may be of wood, and of an suitable configuration, and provided with s oes 11 in the usual manner.

Each runner 10 is rovided, intermediate its ends, with a pair 0 spaced-apart upstanding tie rods 12 engagin at their upper ends through the interme iate portion of an upwardly arched brace strap 13, the latter being outturned at its opposite end and engaging fiat against the upper edge of the adjacent runner 10, and held thereto by clips or straps 14 secured against the opposite sides of the runner 10.

A block 15 is seated upon the upper edge of the runner 10 between the pair of rods 12 and is provided with a substantially T- shaped head which extends transversely of the block, and which is arranged upon the upper end thereof. The block 15 is prov1 ed at its opposite sides with pairs of vertically extending and spaced-apart outstanding ribs 16 providing a space between each pair of the ribs adapted to snugly receive the rods 12 therein. Heads 17, in the form. of sleeves, are seated upon the upper ends of the blocks 15, and corresponding in width to that of the blocks 15. Each head 17 is provided at opposite sides with a pair of vertically extending and spaced-apart ribs 18 adapted to aline with the ribs 16 and en gage against the opposite sides of the rods 12. A clamping plate 19 is placed upon the upper side of the head 17 and is provided with pairs of spaced-apart lugs 20 at opposite sides adapted to register in vertical alinement with the ribs 16 and 18. The lugs 20 hold the plate 19 from longitudinal displacement from between the rods 12. The upper ends of the rods 12 are provided with clamping nuts or the like which engage against the upper side of the strap brace 13, and which bind the base securely against the plate 19, and hold the rods 12 from spreading apart.

The heads 17 are connected by a transversely extending bar 21 which fits snugl in the heads 17 at opposite ends and wine is adapted to slide therethrough. The bar 21 is provided with rows of verticall disposed openings 22 near its opposite on s through which may be secured retaining bolts 23, the latter passing vertically through the inner ends of the heads 17 and through the adjacent end portions of the plate 19. Clamping nuts or the like are mounted upon the bolts 23 to hold the same in position, the bolts 23 securing the heads 17 from longitudinal movement on the opposite ends of the bar 21. The heads 17 may thus be adrods above the block and having a transverse aperture therethrough, said block and head being provided with spaeed-apart vertically extending ribs outstanding from the opposite sides thereof for engagement against the opposite sides of said rods, a transverse brace bar engaging at its end through said head, and means for securing the end of said brace bar adjustably in the head.

2. In a runner mounting, the combination of a pair of upstanding rods adapted to be mounted on a runner, a supporting block arranged between the rods and having vertical guide ays to receive the rods for holding the block from lateral displacement from the rods, a (:(mnecting head resting on the block between lhe rods, brace plates secured to the sides and top of the head and having vertical ways therein to receive the rods, and a clamping element mounted on the upper ends of the rods for binding the brace plates to the head and holding the latter to the block and for maintaining the rods in the vertical guides and ways.
